i have a 1996 F350, 460 fuel injected. i have a valve making some tapping noise, ive tried some oil additives to see if the lifter will free up but no luck. i'm going to put a new set of lifters in it. does these valves have an adjustment or just torque down. any other tips on doing this job will be greatlt appreciated.

 

should be a bolt on arm. would be good to check, never know what previous owners can do.....

 

there just torqued down. Read repair manual and check torque specs. You dont have to have stress off the valves or anything. Just toruqe to spec.

 

I would check their preload when you put the new ones in. I would also put some new valve stem seals on and check the guides out for wear while you have the springs off.
